FIELD OF THE INVENTION

[0001] The present invention relates to an exercise apparatus and particularly a waist trimmer for stretching limbs and building waist and back of human body to healthier conditions.

BACKGROUND OF THE INVENTION

[0002] There are a wide variety of exercise apparatus available on the market these days. Each has some specific purposes and function. For instance, some are for enhancing body endurance, some are for building stronger legs, some are to build arm muscles, some are to strengthen abdomen or waist, etc. However, not much has been developed for stretching waist, abdomen, limbs and back of human body. People usually like to stretch the body, especially the waist, and to relax the muscles when feel physical fatigue. Stretching exercise can eliminate fatigue, and restore physical energy and stamina. On human body, the back muscles generally get least movement and exercise. Many illnesses are related to the back, such as waist muscle pain, neck and shoulder inflammation, sore and ache on waist and back, etc. Hence to give the waist and back suitable exercises is important to the health and well being of people.

SUMMARY OF THE INVENTION

[0003] In view of the foregoing concerns and disadvantages, the primary object of the invention is to provide a waist trimmer to give people's waist and back sufficient stretching and desired exercises so that people can quickly restore physical energy and gain stamina.

[0004] Another object of the invention is to provide a waist trimmer that is adaptable to people of different physical sizes and figures, and gives users full stretching and desired exercises on the waist and back, and becomes more acceptable to more people.

[0005] To attain aforesaid objects, the waist trimmer of the invention consists of a base frame, a positioning mechanism and an exercise mechanism. The base frame is substantially a L-shaped tubular bracket including a transverse tube at the front end, and a left and a right arched tube having respectively a front end attached to a rear section of the transverse tube at two sides proximate to the center thereof and another end directing rearwards and bending upwards to attach to an upper transverse tube. The positioning mechanism allows a human body to lie thereon and includes upright posts located at selected front positions of the left and the right arched tube of the base frame, a seat plate and a seat pad mounted to the top ends of the upright posts, and an anchor plate and a backrest mounted to the upper transverse tube. The exercise mechanism includes an axle yoke attached to the upper side of the transverse tube, a front arched tube housing a front inner tube, a left and a right foot pedal mounted to the top end of the front arched tube, a bucking tube attached to the left side of the transverse tube and housed a coupling tube, and a waist roller. The seat pad has a trough formed in the rear middle section thereof to prevent hitting the bucking tube when the waist roller is raised during exercise. There is a cradle dock located between the left and the right arched tube. A damper is bridged the cradle dock and the bucking tube to allow the waist roller moving downwards slowly without dropping abruptly to avoid incurring uncomfortable feeling to the user so that people can do exercise on the waist and back to get healthier physical conditions.

[0006] By means of the structure set forth above, the invention has the following advantages:

[0007] 1. The left and the right foot pedal, the front arched tube, the bucking tube and the waist roller of the exercise mechanism of the invention form a linkage motion relationship to produce an oscillating movement. Coupling with the feet pedaling motion, the waist roller on the bucking tube can lift user's back and waist upwards. When user's feet stop pedaling, the damper generates a resistant force to allow the waist roller moving downward slowly without dropping abruptly to avoid incurring uncomfortable feeling to the user and to give the user proper exercise on the back and waist and to get healthier physical conditions.

[0008] 2. The invention allows user's limbs to stretch, and give user's waist and back desired stimulus and exercises.

[0009] 3. The seat pad and backrest may be adjusted to various elevations to suit people of different physical sizes, to make use and exercise more convenient.

[0010] 4. The invention has a damper that serves as a buffer and can prevent shock and impact from incurring uncomfortable feeling to human body.

[0011] 5. The waist trimmer may give people's waist and back suitable exercises to mitigate sore and ache on the waist and back.

[0012] 6. The invention can be widely adapted for use in homes, gyms, organizations, recreation and nursing houses for aged people.

[0013] The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

The seat pad 21 has a trough 211 formed in the rear middle section thereof to allow the bucking tube 34 to move therein without hitting the seat pad 21 when a waist roller 35 located at the top end of the bucking tube 34 is raised during exercise. The anchor plate 220 is mounted to the upper transverse tube 12 located at the rear end of the left and right arched tube 11, 11′ for supporting the backrest 22. There are further a left and a right handle bar 221, 222 located at the rear end of the backrest 22 extending outwards from two sides thereof.

[0020] The exercise mechanism 3 further includes a front arched tube 33 mounted to the right side of the axle yoke 30 which is attached to an upper side of the transverse tube 10 of the base frame 1 and a front inner tube 330 housed in the front arched tube 33, a left and a right foot pedal 31, 32 mounted to the top end of the front inner tube 330, the bucking tube 34 mounted to the left side of the axle yoke 30, a coupling tube 340 housed in the bucking tube 34, and the waist roller 35.

[0021] The axle yoke 30 is fixedly mounted to the upper side of the transverse tube 10 and has upward flanges 300 at two ends each has an aperture 301 formed proximate the top end thereof for holding a pivotal shaft 303. The pivotal shaft 303 runs through and supports a bearing tube 302. The front arched tube 33 is mounted to the front end of the bearing tube 302 and extends right wards and upwards. The front inner tube 330 is housed in the front arched tube 33 at the upper end thereof. The front arched tube 33 further has first adjusting holes 331 linearly formed on the upper side to receive a first anchor pin 332 to fasten the front inner tube 330 at a selected location inside the front arched tube 33. The front inner tube 330 has a transverse pin hole 3300 formed proximate the top end thereof for pivotally engaging with the left and the right foot pedal 31, 32 through a pin 333. The bucking tube 34 is attached to the left side of the axle yoke 30 in the center thereof and bent upwards to the left side. The upper end of the bucking tube 34 houses a coupling tube 340 and has second adjusting holes 341 linearly formed on the lateral side thereof to receive a second anchor pin 342 for fastening the coupling tube 340 at a selected location inside the bucking tube 34. The coupling tube 340 has a top end extending upwards to form a rear axle yoke 36. The rear axle yoke 36 has two upward flanges 360 each has an aperture 3600 formed on the top end thereof for pivotally holding a shaft 350 that runs axially through the waist roller 35. The cradle dock 13 is located between the left and the right arched tube 11, 11′ and the damper 14 is bridged the cradle dock 13 and the left and the right arched tube 11, 11′ to allow the waist roller 35 located on the upper end of the bucking tube 34 moving downwards slowly.
